SCRs, SSRs, and SPRs recorded from a test subjects, demonstrating stable waveform of SSRs in response to nonspecific stimuli.

Overview of extracted parameters from the EDA responses that were used in the data analyses_

Parameter	Description	Unit
NS.SCRs_Amp	Amplitude of the nonspecific skin conductance responses	μS
NS.SPRs_Amp	Amplitude of the nonspecific skin potential responses	mV
SPRET	Turning point of the NS.SPRs relative to the NS.SCRs peak	%
NS.SCRs_Trise	Time from onset of NS.SCRs to peak NS.SCRs	S
